Add sentry report preview

It would be interesting to see how that gets formatted.

Also random highjack suggestion is localisation of errors.

Feel free to close it if you think none of these are interesting.

The issue does not name any files, tests, or entry points. Start by locating the Sentry reporting and error-formatting code, then clarify the intended preview format and whether localization is part of the request; done should include an agreed preview behavior and tests for it.
